/**
 * \class CImageOp
 * \brief Image operations interface.
 *
 * There are various image operations that implement this interface, e.g.
 * for rotating, scaling and filtering bitmap.
 *
 * Usage example (CRotationOp):
 * <pre>
 * iSource = ....
 * iTargetMode = EGray256;
 * iTarget1 = CNokiaCVImage::NewL();
 * iTarget1->CreateL(iCurrSource->Size(), iTargetMode);
 * CRotationOp op(iCurrSource, 90);
 * op.DoOperation(iTarget1);
 * ...
 * </pre>
 *
 * This class represents an interface that all image operation classes must implement.
 * Most of the operations implementing this interface are also included in CImageOperations.
 * 
 * \note Symbian MClass.
